niDMM.cs exception: "Device was not recognized. The device is not supported with this driver or version."

[robson]

Hello to everybody!

I've a question about using a DMM (PXI-4065) with VStudio 2008 and Measurement Studio 2009.

Because DMM are not still supported in .Net, I downloaded niDMM.cs wrapper 3.0 from NI web site.

I also downloaded C# Measure DC Volts example to compare it with my application.

Both, example and my application, fail trowing the exception [-1074118656] "Device was not recognized.  The device is not supported with this driver or version." when constructor class is called! 

dmm = new InstrumentDriverInterop.Ivi.nidmm("PXI3::12::INSTR", true, true);

I suppose it's depending on PXI device!

I also tried to use a VISA alias like "pippo" and then I tried to insert an unexistent device name. In any case the same exception has trown.

NI-DAQmx 8.9.5

NI-DMM 3.0.1

NI-VISA 4.6.1

NI-MAX 4.6.2f1

Thank you Matteo

That was the solution!

Now I'm using the name in "NI-DAQmx Devices" MAX tree [PXI1Slot5] instead of the PXI MAX tree [PXI3::12::INSTR].

Best Regards
